Which of the following compounds has the higher melting point? (ignore difference in strength of attractive forces.) H I. VS. II. Select one: O A. I O B. Both compounds have identical melting points. O C. II
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
In case of hydrocarbons , due to branching present in the compound, the surface area of molecules decreases which makes it more compact and sphere like so it will be easier to pack them tightly thus it will be hard to break that compact structure .
